Kurt Busch is a NASCAR driver, but this weekend he's planning on becoming the fourth driver to attempt The Double, racing in both the Indy 500 and the Coca-Cola 600 in one day. He's not so used to IndyCar yet, so this is what can happen when a driver loses his concentration just for a fraction of a second.

Busch was hurtling along at way over 200 miles per hour when he lost grip and slammed, hard, into the wall. And then the back of his car erupted in a showy little fireball. And it's all because he thought, for the briefest instant in time, that one could just cruise in one of these open-wheeled race cars, via USA Today:

"I was starting to feel comfortable. That's when I made the mistake of just letting my guard down or settling into that long run type mentality whereas with an IndyCar you have to be on edge," Busch said. "You have to keep track of where you are at all times and the adjustments in the car. Maybe I just didn't keep up with keeping the car underneath me. Trying to get into that rhythm and feel other things around you and I got behind on my adjustments in the car."

Kurt Busch is a better driver than you, and he let his car get the better of him. Luckily, he was able to walk away from this wreck. This weekend, when you watch the Indianapolis 500, remember that. Merely qualifying for that race is a monumental feat.

Winning is incredible.
